Question for unboosted V6......

O.K. so I'm gonna follow GB the unboosted's suggestion. The front cam's bearing is going to be re-drilled. Right oil galley's feed side 1/8" and the left galley's exit/discharge 3/32".

According to Jim Ruggles, this alone brings up the oil pressure by 15-lbs.

Hey GB...(or anyone else),

Can I get away with just doing this upgrade to the front bearing, or do I have to also drill out the 3-other cam bearings like Jim Ruggles wrote about?

I only did the front bearing and I get 30 psi with hot 5W-30 at idle...then again, mine won't idle below 1200rpm. GB

Yours only idles 300 RPMs more than mine at idle....At 30lbs @1200, that's good enough for me.

Thanks GB!
